Welcome mowersmith! 
If your planing on keeping the mower for a spell I would recommend getting the technical manual from John Deere. They are very strict on their copyright so it's really the only way to get a manual with the exact wiring, any Kawasaki engine changes that were spec'd by Deere plus details of the rest of the mower chassis.
You can order either a CD or a paper version of the technical manual here:

If you are not already aware of it, John Deere's online Parts Catalog is a great tool for finding exploded views and part numbers for your mower:

.. and it's a free place to start your research!
